What is a qdat file and how do I open a qdat file?
The QuickTime Install Cache File is stored in the QDAT format and is affixed with the QDAT extension, and is used by the Quicktime software. These QDAT files are generally classified as proprietary data files that contain installation data used for installing QuickTime. They are used to provide input values like default fonts to the QuickTime installer, which uses those values when writing the QuickTime program to the hard drive. The QDAT file is primarily associated with a file called QuickTimeInstallCache.qdat and accompanied or bundled by an execution file known as QuickTimeInstaller.exe. These data files should be placed in a directory whose name matches the bundle identifier of the app. The software is used for creation and playback of movies and audio. The latest versions of the software are Quicktime 7 and Quicktime X. The Apple QuickTime software can be used in Microsoft Windows-based platforms and Mac Operating systems to access and view the content stored in these QDAT files.
